Apple Inc. proved last night that it is now allowing iPhone, iPad and iPod touch developers to build apps that can make Internet calls over a 3G cellular network.
"We revised our Program License Agreement in conjunction with our revised Software Development Kit for iPhone, iPod Touch and iPad Apps," wrote an Apple spokesperson. "Included in this update is the ability for developers to make VoIP apps that use cellular networks."
VoIP stands for Voice over Internet Protocol -- basically, Web-based telephony.As we reported last night, several VoiP apps have been accepted for use on the iPhone, including iCall and Fring.
Skype, one of the most admired VoIP applications, said it had a 3G iPhone app ready to go, but wanted to get a couple of service information squared away.
Skype is waiting for Apple to explain when the new SDK terms of service for iPhone OS 3.2 SDK beta, which were published yesterday, will go into effect for current iPhone users who are still bound under the terms of iPhone OS 3.12 SDK, according to Skype spokesman Chaim Haas.
